I/InputReader( 304): dispatchTouch::touch event's action is 1, pending(waiting finished signal)=0

Question

To make the listview smoother, I decided to use an array to save view generated by getView () each time to reuse, in order to avoid duplicate getView(), so they inherit the BaseAdapter to write MyBaseAdapter. Ultimately, the effect is very good, very smooth running, buthas given rise to new problems: the button inside of the first and second item of the listview, sometimes the middle one does not respond to the click event, debug the following log:

I/InputReader (304): dispatchTouch : touch events action is 1, pending (waiting finished signal) = 0
I/InputDispatcher (304): Delivering touch to current input target: action: 1, channel 42068da0 com.meet.baby / com.meet.baby.test (server)
I/InputDispatcher (304): Delivering touch to current input target: action: 1, channel TouchIntercepter (server)

But the button click event was able to complement the entry is clicked after implementation.
